Log:
  add a knob that disables detection of write protected disks

  It has been reported that on some systems (with real hardware passed
  through to a virtual machine) the WP detection causes USB disk probing
  failures.

  While here, also fix the selection of the next state in the case
  of malloc failure in DA_STATE_PROBE_WP.  It was DA_STATE_PROBE_RC
  unconditionally even when it should have been DA_STATE_PROBE_RC16.
